Ancient Observatories: Timeless Knowledge

Squeak Challenge Web Activity


Sundial Challenge

Web Activity
Description

Norbert has lost his watch and he needs to be able to tell the time of day so he doesn't miss any important appointments. The ancients could tell time by looking at the direction of the shadow of an object called a gnomon. A gnomen could be just a straight stick or part of a more ornate sundial. The direction of the shadow varies with the time of day so it can be used to tell time. The direction of the gnomon's shadow is simulated in the activity and a protractor is provided so your students can measure angles. There are several challenges in the activity: Angle Challenges, Symmetry Challenge, Measurement Challenge 1, Measurement Challenge 2, Plotting Challenge, Analysis Challenge 1 and Analysis Challenge 2. In this activity, your students will see how scientists study nature's secrets as they learn about angles, symmetry, measurement, plotting and data analysis.

Instructional Objectives

The student will

  • tudy sundials with an engaging and fun Squeak activity.
  • apply the definitions of right, acute, obtuse and straight angles.
  • explore symmetry by comparing sundial shadows.
  • measure directions of shadows for different times of day and latitudes.
  • plot their data using a scatterplot and use the data to explain and predict.
  • work together cooperatively and analyze and present their results.
